A while back, I operated the postfix mail servers for a B2B app. AFAIK the only way to get email from these servers was to work at a company using our product, add your email to the app, and explicitly opt into getting notification emails. And even then, the only emails they'd send were transactional emails; the marketing dept did their own unrelated thing. In spite of this, we semi-regularly found our servers blacklisted for allegedly sending spam. Since then I don't just trust by default when people add things to blacklists.

All this is to agree with the sibling comments; maybe your priors give you a particular default view, but it's not universally shared, and even so Google rather suffers from a long history of banning people in ways that sure look arbitrary and then refusing to say anything about it to anyone, which rather assists in the banned party looking sympathetic.
